The latest News and Information on DevOps, CI/CD, Automation and related technologies.
This series shows you how to get started with infrastructure as code (IaC). The goal is to help developers build a strong understanding of IaC through tutorials and code examples. Infrastructure as Code (IaC) is an integral part of modern continuous integration pipelines. It is the process of managing and provisioning cloud and IT resources using machine readable definition files.
As a DevOps Engineer, one day you’re performing magic in the terminal, settling clusters, and feeling like a god. On some other days, you feel like a total fraud and scam. Errors and bugs appear from everywhere, you don’t know where to start, and you don’t know where to look. Sadly, days like this come far too often. To be more specific, what often causes these bad days is none other than Kubernetes itself.
When the internet first came into existence in 1983, its communication channels didn't exist, and it was just operational enough to be used for research purposes. In 1989, Tim Berners-Lee had the idea to develop a system for the internet using TCP/IP protocols. That public project at CERN introduced HTTP, HTML, World Wide Web (WWW), and a client-server as communication mechanisms. In this post, you'll learn how HTTP protocol works and how new versions brought it to where we are now, with the widely used HTTP/2 in 2021.
An explanation of the meaning of SLA, SLO and SLI, and how SREs should use each concept to manage reliability.
Seasonal spikes in consumer activity are expected, if not depended on, by online retailers throughout the calendar year. However, as shoppers rush to compete over door-buster deals and order holiday must-haves, web traffic escalates to levels standard resource allocation cannot easily sustain. This spike in traffic can lead to unresponsive checkouts, lost or abandoned carts, and slow-loading pages, ultimately resulting in thousands of dollars in lost revenue.
The Internet of Things adoption is growing faster than ever before. As connected devices become more affordable, they find their place in many aspects of our lives. Users worldwide can benefit from a large ecosystem of IoT solutions. However, this rapid growth comes at a cost. Different IoT edge devices have different interfaces, speak different languages and many are not supported soon after manufacturing. Over time, this presents challenges not only to usability, but also to security and privacy.
Automating tests and deployments with infrastructure (CI/CD) more productive. Instead of managing multiple tools and manual processes, all they have to do is commit the code to a code repository. Not everyone on a project visits the CI/CD system, but they may need to know when the build process fails or is successful. This is where a proper handshake between CI/CD systems and project management tools such as Jira shines.
